Abstract

Historic accidental release of mercury-contaminated material associated with nuclear weapons production at East Fork Popular Creek (EFPC) resulted in stream and floodplain contamination. In 1991, the U.S. Environmental Protection Agency (EPA) Environmental Monitoring Systems Laboratory in Las Vegas (EMSL-LV) currently the National Exposure Research Laboratory's Characterization Research Division (CRD-LV) assisted in the Remedial Investigation/Feasibility Study (RI/FS) for East Fork Popular Creek. Specifically, CRD-LV helped to: (1) test the use of field-portable X-ray fluorscence (XRF) as a rapid field analytical method for mercury; (2) design an optimum soil sampling strategy; (3) select and implement a method of estimating mercury concentrations using geostatistical methods; and (4) determine the species of mercury in the floodplain soils using an EPA developmental selective chemical extraction procedure.
